Kate Middleton stepped out in public on Tuesday for a good cause - and for the first time since announcing she is expecting her third child.
The Duchess of Cambridge joined husband Prince William, and brother-in-law, Prince Harry, to celebrate World Mental Health Day.
At a special Buckingham Palace reception, they honored those working in the mental health field and at their Heads Together campaign.
This initiative, headed by Kate, Harry and William, aims to reduce the stigma surrounding mental health issues in the UK and worldwide.
They did not discuss what Kate Middleton's baby gender and name, but her baby bump was ever-so-slightly visible, as you can see below!
